Tbeditablecolumn With (Non Pk) Composite Index?

Hi folks,

I have a database in which there are a number of tables with composite indexes that are not PKs. I am currently using the UniqueAttributesValidator extension to validate this in the rules() function in the model. This is working fine for entering new records via the form but I when I use Yiibooster’s TbEditableColumn class in the ExtendedGridView, I am getting the standard Yii error message.

Is seems that TbEditableColumn is somehow bypassing this validation rule?

I’m at a loss here. Can anyone help me out?

Thanks in advance,
